地质因素对采煤生产的影响和倾斜长壁采煤法采煤技术

Influence of geological factors on coal mining production and coal mining technology with inclined longwall mining method

倾斜长壁采煤法是工作面沿走向布置,沿倾斜方向推进。生产系统简单、工作面搬迁次数少、掘进率低,其应用范围越来越广,是我国煤矿重点推广的开采技术方法。主要阐述了煤矿生产的地质因素对采煤生产的影响,倾斜长壁采煤法采煤系统的类型、采煤系统分析、适用条件及评价等问题。

The inclined longwall mining method is the working surface along the direction of the arrangement and to boost along the tilt direction. The production system is simple,the number of face removal is small,the tunneling rate is low,and its application range is more and more extensive,which is the key mining technology of coal mine in China.This paper mainly discusses the influence of geological factors on coal production,the type of coal mining system,the analysis of coal mining system,the applicable conditions and evaluation of inclined longwall mining method.
